Previous findings report use of the drug ecstasy (MDMA) to be associated with lower emotional intelligence (EI), and compromised functioning in brain areas responsible for emotion. This study explored the relationship between ecstasy use, EI, mood and parenting styles. Questionnaire measures of drug use, lifestyle, parenting style and EI were obtained, with separate IQ measures for fluid...

<i>Aims:</i> This review examined studies of executive functioning in abstinent ecstasy (3,4-methylenedioxymethamphetamine, MDMA) users on tasks which had been empirically mapped onto updating, shifting, inhibition and accessing long-term memory executive processes. Studies of some aspects of visuospatial memory performance were also included because of the investment of executive resources in...

Previous research has demonstrated working memory and executive deficits in recreational users of MDMA (3,4-methylenedioxymethamphetamine; Ecstasy). In turn, both of these constructs have been implicated in syllogistic reasoning performance. Twenty-two MDMA users (mean age = 21.36) and 26 MDMA nonuser controls (mean age = 21.31) were tested on syllogisms of varying difficulty and on measures of...

Abstract Previous research suggests that MDMA users are impaired in various aspects of cognitive functioning, however, it remains unclear whether they might experience deficits in established measures of verbal working memory functioning. In the present study current and previous MDMA users were compared with non‐users on verbal working memory measures including reading and computation span....
